Changed event not working with textbox?

Filtering Enabled, Local script

I'm trying to make it so when the player types in the gui it would replicate onto the surface gui nothing is happening but I'm getting no errors

searchbar.OnScreenText.MouseButton1Down:connect(function()
	local gui = script.SearchGui:Clone()
	gui.Parent = game.Players.LocalPlayer.PlayerGui
	gui.SearchGuiBox:CaptureFocus()
	searchbar.OnScreenText.Text = ""
	
	spawn(function()
		searchbar.OnScreenText.Changed:connect(function(Text) --This line
			wait(.1)
			if gui and gui:FindFirstChild("SearchGuiBox") then
				searchbar.OnScreenText.Text = gui.SearchGuiBox.Text
				search(gui.SearchGuiBox.Text,false)
			end
		end)
	end)
	
	searchbar.SearchEnter.MouseButton1Down:connect(function()
		search(searchbar.OnScreenText.Text,true)
	end)
	--Player types some poopy stuff
	gui.SearchGuiBox.FocusLost:connect(function(enter)
		if enter then
			search(gui.SearchGuiBox.Text,false)
			gui:Destroy()
		else
			searchbar.OnScreenText.Text = gui.SearchGuiBox.Text
			gui:Destroy()
		end
	end)
end)
